T0 at whom it may concern: 7

Be it known that I, OTTO EWERT, of Cleveland, in the county of Cuyahogaand State of Ohio,have invented certain new and useful Improvements inVapor-Burners; and I-do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in vapor-burners in which theburner is of the Argaud variety, with perforated tubes arranged,respectively, inside aud outside the wick, the inner perforated tubehaving a diaphragm inside thereof and extending laterally across thebore of the tube, to arrest the current of air passing up inside theburner and deflect the same .into the flame, to the end that betterresults are had by means of the diaphragm.

In the accompanyingdrawings, Figure l is aside elevation of avapor-burner embodying my invention. Fig. 2 is an elevation in section,taken at right angles to the view shown in Fig. 1. Fig. 3 is a planview.

A represents a container, with an inside tube, A, the two being unitedor integral at the bottom and having an opening, A, to admit air insidethe burner ou the Argand principle. The tubular projections a are forattat-hing feed-pipes and supporting the burner. The wick B is usuallyinclosed in a gauze or perforated metal casing, b, the latter beingengaged by the spur-wheel b, by means of which the wick is elevated ordepressed uniformly. A perforated tube, O, is made to fit into the upperend of the tube A, and consequently elevated position.

the tube 0 is inside the wick. An outer perforated tube, D, ineloses theupper end of the wick. The tube D is secured to a band or holder, D, thelatter being secured to or carrying pins (2, that pass through holesmade in ears a of the container. A forked lever, E, is pivoted to anarm, F, the latter being secured to the container. The prongs of thelever abut the lower ends of the pins, by means of which, by pressingdown on the outer end of the lever, the tube D is raised for the purposeof lighting or extinguishing the burner. Inside the perforated tube 0,and located usually near the top thereof, is a diaphragm, Q, the latterextending laterally across the bore of the tube. The diaphragm arreststhe current of air that passes up inside the burner and deflects the airinto the flame, thereby greatly increasing the effectiveness of theburner.

In the drawings the tube D is shown in its \Vhat I claim is In avapor-burner of the Argand variety,

the combination, with perforated tubes lo cated, respectively, insideand outside the wick, as shown, of a diaphragm made to extendlaterallyacross the in'li'ei' perforated tube, substantially as set forth.

In testimony whereof I sign this specifica tion, in the presence of twowitnesses, this 18th day of October, 1886.

OTTO EWERT'.
